LAWN-SPRINKLING DEVICE.

Specileation of Letters Patent.

Application filed J une 13. 1911. Serial No. 632,967.

This invention relates to lawn sprinkling y devices, and more particularly to that special class of lawn sprinkling means or devices which is or are permanently installed in position for use and service, being suitably connected with piping for supplying water.

In accordance with the present'invention, l provide a sprinkling or spraying device for lawns which comprises an immovable member set into the turf, and a movable member co-acting therewith and provided with a specially organized partor portion for effectual spraying or sprinkling-such latter part or portion being normally chambered within and p roteeted'by the immovable member. This movable member is projected into operative position above the turf by the force of the head of water supplied to the device by a suitable service pipe, and when the head of water is cut od the movable member drops into housed position within the immovable member, within which it is thoroughly protected against damage or deterioration, and presents no obstruction to traverse of the lawn.

The invention has for its object to provide improvements in lawn sprinklers or sprayers of the general character stated which will be superior in point of 'relative sim plicity and inexpensiveness of construction, positiveness in operation, length of life and durability, freedom from liability of damage or disruption and convenience in installation, and which will be generally superior in eiiciency and serviceability. I.

With the above and other objects in view, the invention consists in the novel revision, formation, construction, combinatlon, association and relative arrangement of parts, members and features, all as hereinafter described, shown in the drawing, and finally pointed out in claims. i

In the drawing Figure 1 1s"a top plan view of a lawn sprinkling or spraying device constructed and organized in accordance with the invention; Fig. 2 is a central verticaly sectional elevation of the same, taken upon the line 2 2, Fig. 1, the device being shown as installed in a turfed lawn, the parts being in inoperative position; Fig. 3 1s a view similar to Fig. 2, the parts being shown inf' operative position; Fig. 4 is a detail transverse sectional view, taken upon the line lm/l', Fig. 3, and looking in the direction of the appended arrows; and Fig. 5 is a partial detail transverse sectional view taken upon the line 5 5, Fig. 3, and looking in the direction of the appended arrows.

Corresponding parts in all the figures are designated by the same reference characters.

Referring with particularity to the drawing, A. designates the immovable member and B designates the movable member of a sprinkling device or sprinkling or spraying means organized and constructed as desired,

the immovable member being installed in the lawn formation in connection with a suitable service pipe notshown, extending beneath the surface of the lawn, which is designated at' C, c designating spears of grass which, as shown in Fig. 2, may overlie both members A and B when the movable member is in lowered or inoperative posi-' 'directing portion b is formed to'cause the rotation of the member B and thus elfect or enhance the performance of distributing the water as last stated. The impact of the water upon the water directing portion I) causes the rotation of the member B. The member A comprises a tubular body 6 which is connected with the servici pipe as by a threaded coupling 7, and is provided at its upper end with a tubular easing 8 the upper portion of which is open and installed so as to be flush with the surface of the lawn formation. The member B comprises a tubular stem 9 beneath the lower end of which is secured a wire loop 9 as a guard to prevent the stem 9 from displacement, the stem 9 11C PatentedNov. 1l, 1913.e

' being of smaller external diameter than the internal diameter of the tubular body 6, and carrying at its upper end the water directing portion b which is mounted upon the stem 9 by a bearing device D which enables the portion b to rotate upon the upper end of the stem 9. Normally, the stem 9 is chambered in the body 6, and the portion b and the bearing device D are chambered in the lo casing 8, the bearing device D limiting the downward movement of the member B when the latter is in chambered position, by engagement of the bearing device D with the bottom of the tubular casing 8. The tubular casing 8 is of enlarged diameter, with relation to the tubular body 6, and the bottom portion of the former, eXteriorly of the body 6, is provided with a plurality of openings 10 which permit water or other substances 'collecting in the casing 8 to pass downwardly out of said casing and into .the earth. The lower end of the casing 8 is provided with a downwardly extending tubular nipple 11 within which is threaded, at its upper portion, a tubular nipple '12, the lower portion of said nipple 12 being spaced from the lower portion. of the nipple 11 so as to permit the tubular body 6 to be engaged with the same threads, as 13a, whereby the nipple 3o 12 at its upper portion is threaded to the nipple 11. The lower portion of the tubular nipple 12 is formed into a conical valve s eat l2a ground to fit a corresponding conical valve or head 12b fitted to the lower end of the tubular stem 9. The valve Ior head 12b is seated upon the valve seat 12a when the stem 9 is in raised position, A. slight play is allowed between the valve head 12b and the inner wall of the bodyv6, and between the stem 9 ,and the inner wall of the tubular nipple 12, to prevent clogging of the movement of the member B, as by sand or other foreign substances, which are permitted to escape through the small spaces provided between the stem 9 and the nipple 12 and between thechead l2b and the body 6. The lower end of the body 6 is disposed in a plane slightly above theV lower conical portion of the valve head 12", when the same 5o is in extreme lowered osition, and is countersunk or beveled slightly to conform to the conical formation of the valve head 12". Into the upper end of the stern 9 is screwed a tubular bearing member 13 which projects above the upper end of the tube 9 and is surrounded by an annular bearing member 14, having -a base flange l5 which rotates upon the upper end of the stem 9; the bearing member 14 being held to the 6o bearing member 13 by a lock-nut 16 threaded upon the upper end of the bearing member 13. The parts 13, 14 and 16 constitutel the bearing device D and are preferably formed of suitable material to withstand corrosive and' erosive action. Threaded "Lor/enea upon the annular bearing member 14, eX- teriorly of the same, is a base-ring 17 from which rise two diametrically opposed curved deliectors or blades 18, having opposite vertical curvature and transverse outer edge 7 0 curvature as shown in Fig. 5, said blades expanding laterally upwardly and in erging into a conical flat-topped crown 19. The parts 17, 18 and 19, together with lan adjustable water regulating and spreading device ha, constitute the water directing portion b; said device ba consisting of a downwardly directed conical head 20 disposed centrally between the` plates or blades 18 directly over the upper end of the tubular so ,bearing member 13, and having a screwshank 21 threaded in a suitable chamber in the conical'crown 19, so that the head 20 may be adjusted toward or away from the upper end of the bearing member 13 through 35 which water issues after traversing the tubular -stem 9. The water striking'upon the conical head 20 is directed thereby to the curved plates or blades 18 which causes, by re-action, rotation of the water directing 90 portion b, and projection of the spray or finely divided water laterally from the portion b and over the lawn surface, the baseriiig 17 and bearing member 14 rotating upon the bearing member 13. The uality of the spray, and the nature of its de ection or direction by the portion b, will be determined by the position of adjustment of the conical head be.

When the head of water is turned off, the parts will be in the positions shown in Fig. 2, with the stem 9 chambered in the body 6, and the water directing portion Z) chambered in the casing 8. When the water is turned on, it urges the stem 9 with the por- 105 tion 7) upwardly, projecting the parts of the member B into the positions shown in Fig. 3, the valve head 12b acting as a piston under impact of the water. When the valve head contacts with the valve seat l2, all of 110 the water is forced to pass through the stem 9 and the tubular bearing member 13 so as to be directed against the plates or blades 18 and the conical crown 19, causing rotation of the water directing portion b., as 115 above statedA and a broad scattering or spraying of the finely divided water over the lawn surface. When the waterv is turned ofi", the member B and its parts drop into housed positions, as above stated, and as shown in Fig. 2, wherein they are eii'ectually protected from damage or deterioration, the uppermost portion of the same being iush with the surface of the lawn formation C.' The Severalparts and members may be readily taken apart for cleansing or repair, or for packing, and the thread formations are such that rotation of the member B tendsto cause a tightening of the several threaded connections. 1 an imanes i vices, Serial Number 655,584.
